Does living together before marriage affect divorce risk? What studies find

“Wouldn’t living together first help us find out whether marriage will work?” It is an understandable question. Sharing a home reveals habits, bills, schedules, and differences that dating can hide. But learning somebody’s routines and choosing a lifelong commitment are not identical. And what should couples who already live together make of the research?

I am Ricardo Martins. I do not want to turn a journal article into a weapon against your relationship, or offer reassurance the evidence cannot support. Through The Legendary Couple, O Casal Legendário, Vanessa Lima and I speak from a Christian understanding of marriage as covenant. That is our faith commitment. It should not be dressed up as a statistical finding.

The research answer is more complicated than either popular slogan. American studies reach different conclusions depending on age, the timing of commitment, and how marriage histories are analyzed. Cohabitation does not guarantee protection from divorce. A shared address before the wedding does not establish a particular family’s destiny, either.

What the research found

1. Kuperberg: when did the shared life actually begin?

Arielle Kuperberg’s 2014 study in the Journal of Marriage and Family analyzed 7,037 participants from the 1995, 2002, and 2006–2010 waves of the U.S. National Survey of Family Growth. Her methodological question matters: should researchers compare people at the same age at marriage, or at the same age when they first began living together?

Imagine two people beginning a shared household at similarly young ages. One marries immediately; the other marries later. Looking only at wedding age can make those beginnings appear more different than they were. For premarital cohabiters, many marriage-like responsibilities started when the shared household began, not when the wedding happened.

Kuperberg found that age at first coresidence explained a substantial part of the higher dissolution risk associated with premarital cohabitation. When comparisons were standardized by age at coresidence, the difference between cohabiters and direct marriers was much smaller. In some models, it was not statistically significant. This does not mean age explains everything. It means the way we compare relationships can change the apparent answer.

2. Rosenfeld and Roesler: early marriage is not the whole timeline

Michael J. Rosenfeld and Katharina Roesler’s study, published in the 2019 volume of the Journal of Marriage and Family, combined six waves of the same national survey. Its abstract reports 216,455 couple-years, not 216,455 couples. Couple-years add up observation time across marriage histories; they are not a participant count.

The data represented U.S. women aged 44 and younger in first marriages, with histories covering 1970–2015. The abstract consulted does not state the number of women, so I will not invent that sample size. The researchers analyzed retrospective histories. They did not randomly assign people to live together or marry without first sharing a home.

They found lower dissolution rates during the first year of marriage among premarital cohabiters, but higher rates later on. They interpreted the early pattern as a possible benefit of experience living together, not evidence that this advantage necessarily lasted. Their broader conclusion was that an early benefit could conceal a longer-term association with instability.

That time distinction matters. Studying newlyweds alone and studying longer marriage histories need not produce the same picture. But even a sophisticated model of those histories does not remove every difference between the people who choose different paths into marriage.

3. Rhoades, Stanley, and Markman: commitment before the move

Galena K. Rhoades, Scott M. Stanley, and Howard J. Markman’s 2009 study in the Journal of Family Psychology used a random telephone survey of 1,050 people who had married within the preceding ten years. Those were individual respondents, not 1,050 couples interviewed together.

People who began living together before engagement reported lower marital satisfaction, dedication, and confidence, as well as more negative communication and greater divorce potential, than people who moved in after engagement or waited until marriage. The differences were generally small. There were no significant differences between the after-engagement group and those who had not cohabited before marriage.

The pattern could not be explained by the variables examined, including age, income, education, religiousness, and marriage length. Still, reported divorce potential is not the same thing as observing future divorces. Statistical adjustment is not random assignment. The study draws attention to the timing of commitment; it does not establish a universal rule that predicts any individual marriage.

Why the scholarly disagreement belongs in the answer

In a comment published in the journal’s 2021 volume, Wendy Manning, Pamela Smock, and Arielle Kuperberg challenged aspects of Rosenfeld and Roesler’s modeling. Their alternative analysis found a weaker association for more recently married couples, and no association between cohabiting with a future spouse and instability in recent marriage cohorts.

Rosenfeld and Roesler replied in the same journal. They defended their earlier conclusions and challenged their critics’ data filters and treatment of time. Both contributions belong in an honest account. The abstracts of these additional analyses do not give a separate participant count; I am citing them as context for the debate, not presenting them as independent new samples.

All the central studies discussed here concern the United States. That makes them relevant to an American conversation, not timeless laws across every culture or generation. Financial conditions, religion, and who selects into cohabitation can differ. Analyses of marriages also do not represent every cohabiting relationship that ended before a wedding. That selection matters when interpreting what “trying it first” means.

What this changes in practice

1. Ask about the future, not only household compatibility

Learning how someone handles dishes or laundry is useful. It cannot substitute for asking whether you want the same commitment. Talk specifically about fidelity, children, faith, money, and what responsibility means when the relationship becomes difficult. Both people need room to answer honestly instead of agreeing to keep the peace.

Try this question: “What do you believe we are building?” One person may say “a family” while the other says “we’ll see.” That difference exists even if sharing rent feels easy. Identifying it is not a verdict on either person. It is information you need before making larger promises.

2. Do not let the lease answer for you

An expensive apartment, an expiring lease, or the convenience of a move can create momentum. Before packing boxes, name the meaning of the decision. This is a pastoral recommendation consistent with taking commitment seriously, not a causal effect calculated by the studies above.

If you already share a home, the conversation is still available. You do not need to pretend the past was different in order to become more intentional now. Ask what each of you freely chooses today. A shared financial obligation should not be mistaken for a shared understanding of the future.

3. Replace the threat of statistics with preparation

“Research says we’ll get divorced” is not a constructive opening. A better approach is to seek responsible pastoral support or couples guidance suited to your needs. Bring concrete questions rather than asking someone to pronounce your relationship safe or doomed.

How do you handle disagreements? Can you discuss spending without secrecy? Does each person respect the other’s boundaries? Preparation is not an insurance policy against divorce. It is an opportunity to notice expectations that a wedding celebration will not automatically reconcile.

You can be sincerely in love and still avoid necessary conversations. Naming a conflict is not betraying the relationship. It can be a way of treating the commitment with more respect than vague optimism would.

4. If you are already married, care for the marriage you have

Your former address should not become ammunition every time you argue. Focus on the present: what weakens trust now, what responsibility belongs to each person, and what can change? A healthy commitment needs truth and willing participation, not pressure to prove devotion.

Where there is violence, intimidation, or coercion, safety and specialized support come first. Neither religious language nor a statistical association should be used to demand exposure to danger. Discussing marital stability does not mean protecting the appearance of a relationship at any cost.

Where biblical wisdom meets the question

In Luke 14:28, Jesus asks: “Suppose one of you wants to build a tower. Won’t you first sit down and estimate the cost” (NIV). The context is the cost of discipleship, not a study of cohabitation. Without forcing the passage, its picture invites seriousness about consequential choices rather than unexamined momentum.

Matthew 5:37 says: “All you need to say is simply ‘Yes’ or ‘No’” (NIV). Jesus is teaching truthful speech. Applied carefully to relationships, that calls us away from convenient ambiguity. Clarity does not authorize controlling a partner. It asks both people to speak honestly about the promises they are willing to make.

My Christian view of covenant does not depend on making observational data prove more than they can. Faith can name a moral conviction while research remains open about uncertainty. People deserve both honesty and compassion, not a prediction delivered as a label.

The moving box does not decide your future. The more useful question is what you are choosing to build with truth, freedom, and responsibility.
